I was driving on I-88/I-290 w/ my girlfriend around 5:45PM CST.. she said "Did you see that?" and described a green flash. I didn't see it. but then a 2nd one occurred.. in the sky, a big green flash, kinda hazy looking (maybe it was hazy in the sky, dunno.. it was kind of dark). Anyone else see this, or know what it was?? Kinda scary, given the state of alert we're in.
